Abstract

Différents terminaux de communications sont reliés par l'intermédiaire d'une radio large bande à un réseau de communications à l'un des trois niveaux de tailles de cellules d'une hiérarchie immeuble-agglomération-région. Presque tout le trafic de communications passe, à l'intérieur de 'picocellules (1)' du niveau le plus bas, entre des 'stations de base (11)' bon marché équipées d'un émetteur-récepteur radio (111), de quatre émetteurs-récepteurs optiques (112), d'un commutateur ATM (113) et d'un contrôleur ATM (114). Chaque 'station de base (11)' locale est interconnectée à un 'commutateur de central d'extrémité (12)' où est réalisée une connexion avec un réseau fédérateur (4) de communications mondial, à lignes de communications filaires/fibres optiques sur un réseau maillé multi-saut (100) par l'intermédiaire de liaisons optiques (10) courtes, directionnelles, large bande, en espace libre, et hautement focalisées. Grâce à cet accès large bande, non filaire, en espace libre, il n'y a plus besoin de desservir les abonnés ou les utilisateurs au moyen d'un nouveau câblage d'accès large bande de 'dernier kilomètre'. Le service offert à l'abonné permet des pointes d'environ 20 Mb/s et un débit moyen de 10 Mb/s.
